Luczak - Web page: https://patentgrep.com/patent/US5345906A ## CPC - F02M 69/04: Injectors peculiar thereto - F02M: SUPPLYING COMBUSTION ENGINES IN GENERAL WITH COMBUSTIBLE MIXTURES OR CONSTITUENTS THEREOF ## Abstract An injection apparatus for delivering material from a first location to another location under pressure through a series of passages is disclosed herein. The injection apparatus is comprised of an injector body (10) which can be coupled to a pressurization means (50). The injector body (10) is comprised of top (12), middle (14) and bottom (18) plate-like members, the middle members (14) having linear indentations (16) chemically etched upon their surfaces, the linear indentations (16) creating a series of passages (40) upon stacking the members in precise order. The passages (40) serve as routes for delivering material from a first location to one or more other locations. The pressurization means (50) facilitates the movement of material throughout the injector body (10) of the present invention. ## Claims ### Claim 1 An apparatus for uniform injection of material comprising: (a) a generally planar body member, said body member having first and second sides, said body member including outlet cavity means for dispensing material, said outlet cavity means having a defined boundary, said body member including inlet cavity means for receiving material; and (b) a plurality of passages, each said passage including an inlet port and an outlet port, each said inlet port opening into said inlet cavity means, each said outlet port opening into said outlet cavity means, said outlet ports disposed around said boundary of said outlet cavity means. ### Claim 2 (depends on 1) An apparatus as recited in claim 1, further comprising: (a) a feed port, said feed port opening into said inlet cavity means; and (b) pressurization means for pressurizing material in said inlet cavity means. ### Claim 3 (depends on 2) An apparatus as recited in claim 2, wherein said pressurization means comprises: (a) a cylinder body, said cylinder body having first and second ends, said cylinder body having a piston cavity extending between said first and second ends, said first end of said cylinder body disposed within said inlet cavity means; (b) a piston, said piston slidably disposed within said piston cavity; and (c) means for reciprocating said piston. ### Claim 4 (depends on 3) An apparatus as recited in claim 3, wherein said apparatus is configured and structured for positioning between a cylinder head and a block of an engine. ### Claim 5 (depends on 4) An apparatus as recited in claim 4, wherein said apparatus is composed of a plurality of generally planar members. ### Claim 6 An apparatus for uniform injection of fuel into an internal combustion engine, comprising: (a) a generally planar body member, said body member having first and second sides, said body member including outlet cavity means for dispensing fuel into a combustion chamber, said outlet cavity means having a circumference, said body member including inlet cavity means for receiving fuel; and (b) a plurality of fuel passages, each said fuel passage including an inlet port and an outlet port, each said inlet port opening into said inlet cavity means, each said outlet port opening into said outlet cavity means, said outlet ports disposed around said circumference of said outlet cavity means. ### Claim 7 (depends on 6) An apparatus as recited in claim 6, further comprising: (a) a fuel feed port, said fuel feed port opening into said inlet cavity means; and (b) fuel pressurization means for pressurizing fuel in said inlet cavity means. ### Claim 8 (depends on 7) An apparatus as recited in claim 7, wherein said fuel pressurization means comprises: (a) a cylinder body, said cylinder body having first and second ends, said cylinder body having a piston cavity extending between said first and second ends, said first end of said cylinder body disposed within said inlet cavity means; (b) a piston, said piston slidably disposed within said piston cavity; and (c) means for reciprocating said piston. ### Claim 9 An apparatus for delivering a quantity of material comprising: (a) a plurality of generally planar members, each of said members having a plurality of surfaces, said members further being divisible into top, middle and bottom members; (b) said middle members having a pattern placed upon said surfaces, said pattern being similar on each of said middle members; (c) said top, bottom and middle members being coupled together, said pattern upon said middle members communicating to create a passage for allowing said material to travel through; (d) said passage communicating between an inlet cavity means and an outlet cavity means formed in said apparatus. ### Claim 10 (depends on 9) An apparatus as recited in claim 9, further comprising: (a) a fuel feed port, said fuel feed port opening into said inlet cavity means; and (b) fuel pressurization means for pressurizing fuel in said inlet cavity means. ### Claim 11 (depends on 10) An apparatus as recited in claim 10, wherein said fuel pressurization means comprises: (a) a cylinder body, said cylinder body having first and second ends, said cylinder body having a piston cavity extending between said first and second ends, said first end of said cylinder body disposed within said inlet cavity means; (b) a piston, said piston slidably disposed within said piston cavity; and (c) means for reciprocating said piston. ### Claim 12 (depends on 11) An apparatus as recited in claim 11, wherein said patterns upon said middle members are comprised of a plurality of indentations. ### Claim 13 (depends on 12) An apparatus as recited in claim 12, wherein said indentations upon said middle members vary in depth. ### Claim 14 (depends on 13) An apparatus as recited in claim 13, wherein said apparatus is positionable between a cylinder head and a block of an engine.
